Working Principles

The TPS3110E15DBVTG4 operates by comparing the monitored voltage at the THRES pin with the internally generated reference voltage. If the monitored voltage falls below the threshold, the output pin (OUT) is pulled low, indicating a voltage fault condition. Conversely, when the monitored voltage rises above the threshold, the output pin is released, indicating normal voltage levels.
